ENGINE-STARTER.

.BECIFICTON forming part of Letters Patent No. 332,197, dated December 8, 1885.

Application filed August 4. 1885,

To @ZZ whom it may concern:

Beit known that l, GEORGE J. GooDHUE, of Stevens Point, in the county of Portage, and in the State of Wisconsin, have invented certain new and useful Improvements inEngine-Starters; and I do hereby vdeclare that the following is a full, clear, and exact description thereof.

My invention relates to devices for starting 1o t-he fly-wheel of a stationary engine when the crank of the connecting-rod has stopped on a center, 'or for moving the wheel for any purpose; and it consists in certain peculiarities ofconstruction, as will be more fully set forth hereinafter.

In the drawings, Figure l is a perspective view' of the fly-wheel of an engine with one form of my device applied thereto in position `to move said wheel off the dead-center. Fig.

zo 2 is a plan View of another form of my device .applied to the rim of a wheel, thelatter being shown in section. Fig. 3 is a detail sectional view of the form of starter shown in Fig. l, but 'with the cam shown against the outer Vperiphery. ofthe wheel. Fig. 4 is a detail of still another form, illustrating the extensionyoke; and Fig. 5 is a detail of the gripping cam.

Heretofore in many instances the periphery 3o of the iy-wheel has been cast with al series of holes at given' distances apart, so that when the said wheel stopped on a center, or when, for any reason, it was necessary to lmove said wheel, as when the steam is off, this could be done by inserting a rod in one of said holes and turning the wheel thereby; but this is awkward and requires a great expenditure of strength and the efforts of a number of men, and when the periphery of the wheel is smooth .io still greater force and labor are required, and

when there is a little steam left in the cylinder the operation is attended with considerable danger.

The object of my invention is to obviate all 4 5 this, and to provide a simple, easy, and efficacious means for turning the said iiy-wheel when required.

A represents the fly-wheel of a stationary engine; B, its shaft; C, the crank, and D the 5o connecting-rod. E is a fulcrum, of any ordinary construction, as shown, for supporting Serial No.173,508. (No model.)

my device, which latter consists of thesocket F, having lever G inserted in its open rear end, and with a ball, H, in its partly-closed front end, the under side of said front end being ping-cam, to be next described.` The inner surface ofthe frontend of the socket F is of course rounded, as shown, to correspond with the ball H.

The gripping-cam I (shown in detailin Fig. 5) has a short shank, t', and a bifurcated end, I', and the part H of the union-ball is inserted between the forks of this end and secured therein by the bolt z, which passes through perforations in said parts H and I', so that '0 there will be plenty of room for free play on said bolt i', as shown in Fig. 3. The operative end of said cam I is ground flat in a series of transverse bearing-faces, t2 i2, each about half an inch wide, which gives agreater degree of pressure or grip against the smooth periphery or the side of the rim of thefwheel A, and the other end of said cam is provided with a transverse perforation, i3, to receive a shoulder-bolt, k, the said perforation and 8c that part of the bolt k which rests within it being each perfectly round and smooth, while beyond this point the bolt k is screw-threaded and tapped into a screw-threaded perforation -i'n the yoke K, so that the cam I is practically 85 pivoted on the bolt k and can swing freely thereon. The yoke K is formed with an end eX- tension, K', (cast solidly therewith in the forms shown in Figs. l, 2, and 3,) and this part K (which is at a right angle to the length 9o of the yoke proper) is transversely perforated to receive a screw, L, for the purpose of adj usting the yoke to different widths of wheelrims, the said bolt being tted with a set-nut,

Z, so that it will remain stationary after adjustment.

In Figs. l and 3 I have shown the simplest form of my device, adapted especially for narrow-rimmed wheels, and in these forms the yoke is solid with its extension. In Fig. 2 roo I also show a solid yoke, but have added (for wheels having wider rims) the guard M, consisting of an angle-piece of iron of the shape shown, which is perforated to receive the screw L, and which has also another perforation to receive a tap-screw, N, passing also into a threaded perforation inthe yoke end K', for greater security, the guard M ending in an inward projection, m, which bears against the inner surface of the wheel-periphery and prevents the said part from slipping away from position, as might happen with wide-rimmed wheels with the form of device shown in Fig. l.

InFig. 4 I have made still further provision for very wide rimmed wheels, wherein I have illustrated the extension K as being constructed with a sleeve which slides upon the long arm of the yoke K, so as to be adj usted to any distance required, the said sliding extension K being secured in the desired adjustment by holes k in the part K, and. pins vk2, passing through these holes and corresponding holes in 'the part K, as shown in full lines, or by a set-screw, k3, as shown in dotted lines in said Fig. 4. or by any equivalent fastening device, as desired. In this form, I usually make the long bar of the yoke of wroughtiron or steel, and instead of using the described shoulder-bolt lc, I may bend the end of the said long bar around (suitably reduced and rounded of course) so as to form a pivot,

lr, for attachment to the cam I, as an equivalent for the bolt lc, and secure the cam I to place thereon by a pin, as shown.

The operation of my device will be readily understood from the foregoing description of its construction. When it is desired to start the wheel A, the parts being, for instance, in the relative position, shown in Fig. 1, the socket F is rested on the fulcrum IkE, and the yoke and cam placed against the wheel-rim, as shown.l N ow, by raising the outer end ot' the lever G the yoke will slide down on the wheel-rim, (the cam I moving upward enough to permit this movement.) and then the bearing-faces i2 of the cam will tightly grip against the side of the rim of saidwheel, (holding the same tightly between the cam and the screw L,) and as the lever G is depressed the wheel will be turned. The ball-union7 H h H and the slot 1*" in the socket F `enable the parts to have free play and accommodate themselves to the different distances between the point of contact of the cam, &c. as the wheel andthe fulcrum-point of said socket on the wheel is turned, so that the fulcrum does not need to be moved if more than one movement has to be given to the wheel.

It will be seen that my device is equally well adapted to bear against the sides of the wheel-rim as it is against the outer and inner peripheries'thereof, and either form shown may be modified in this respect and made ad j ustable either way, without departing from the spirit of my invention.

If desired, other forms of connection than the union-ball shown may be employed t0- unite the lever and cam; but it is desirable between said cam and the screw of the yoke,

substantially as set forth.

2. In an engine-starter, the combination of the lever and socket and bearing-cam, connected by a union-ball with a yoke pivoted to said cam, and having anrextension provided with an adjustable screw, and a guard adapted to bear against the inner periphery of the iiy-wheel of the engine, substantially as set forth.

3. In an engine-starter, the combination of the lever and socket and bearing-cam, connected by a union ball with a yoke pivoted to said cam, and having a sliding extension secured thereto, provided with an adjustable screw and a rim guard, substantially asset forth.

4. An engine-starter consisting of a lever and bearing-cam, united by a yielding connection, in combination with a yoke pivoted to said cam and adapted to bear against the rim of a wheel on the side opposite to that surface which comes in contact with the cam, substantially as set forth.

In testimony that ,Iclaim the foregoingI have hereunto set my hand, at Milwaukee, in the, county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
